The use of hydropower potential of the rivers of Moscow basin

Exploitation of hydropower potential in alpine areas undermines the ecological integrity of rivers. Damming and water abstraction substantially alter the physical habitat template of rivers, with strong repercussions on aquatic communities and their resources. Tools are needed to predict and manage the consequences of these alterations on the structure and functioning of macroinvertebrate communities and resource availability in alpine streams. We developed habitat preference models for taxa, functional feeding guilds, and organic resources to quantify the effects of discharge alteration on macroinvertebrate communities in two alpine streams. Our physical habitat model related an indirect measure of bottom hydraulic forces (FST hemispheres) to the distribution of macroinvertebrate taxa and their resources. We observed that flow-dependent habitat availability for macroinvertebrate communities generally decreased with increasing water abstraction. We were able to relate these changes to near-bed hydraulic conditions. Our results suggest, however, the existence of upper discharge thresholds delimiting optimal habitat conditions for taxa. In contrast, we found weak effects of near-bed hydraulic conditions on resource distribution. Overall, our findings contribute towards predicting the impacts of water abstraction on macroinvertebrate communities in small alpine streams and the benefits of baseflow restoration.

There's no doubt that nowadays detrital zircon U-Pb geochronology is actually required method of sedimentary basins analysis. Furthermore, this approach may have a lot of applications, such as a stratigraphic correlation. Here we present the first results of U&#8211;Pb LA&#8211;ICP&#8211;MS dating of detrital zircon from the Permian-Triassic red beds located within the Moscow Basin of the East European platform. Two outcrops have been studied: the Zhukov Ravine P/T boundary reference section and the Nedubrovo strata with uncertain stratigraphic position (uppermost Permian or lower Triassic?).U&#8211;Pb ages of detrital zircon grains have been obtained for two samples &#8211; the Upper Permian and Lower Triassic age, which were taken in the proximity to the Permian&#8211;Triassic boundary in the Zhukov Ravine. Corresponding age distributions show contrasting provenance of the studied sedimentary rocks, pointing out that principal change in source of clastic material occurred on the Paleozoic-Mesozoic boundary. It means that detrital zircon U&#8211;Pb geochronology can be used as an additional independent tool for stratigraphic correlation of the Permian-Triassic red beds, at least within the Moscow Basin. We demonstrate this in the case of the Nedubrovo section with debated (Permian or Triassic?) stratigraphic position: the obtained data on detrital zircons persuasively suggests Early Triassic age of the Nedubrovo strata.This study is supported by the Russian Foundation for Basic Research (project no. 18-05-00593).

Diverse Context

Considering the lack of a comprehensive assessement of hydropower potential in the Upper Indus basin, we developed and implemented a systematic framework to explore four different classes of hydropower potential. Our framework uses high-resolution discharge generated by a coupled cryosphere-hydrology model as the bio-physical boundary conditions to estimate theoretical potential. Thereafter, diverse context-specific constraints are implemented stepwise to estimate the technical, economic and sustainable hydropower potential. The successive classes of hydropower potential integrate considerations for various water demands under the water-energy-food nexus, multiple geo-hazard risks, climate change, environmental protection, and socio-economic preferences. We demonstrate that the nearly two thousand Terawatt-hour of theoretical potential available annualy in the upper Indus can be misleading because a majority of this is technically and economically not viable. Even smaller potential remains if we account for the various sustainability constraints that vary spatially. Our concept of the sustainable hydropower potential enables decision makers to look beyond the energy sector when selecting hydropower projects for development to achieveenergy security under the Sustainable Development Goal 7 (SDG7).The generated portfolio of sustainable hydropower projects is superior to the current portfolio based on outdated studies because our method looks beyond theoretical possibilities and excludes projects that conflict with management objectives under other SDGs. The spatial maps with potential and the cost curves for hydropower production provide a science-based knowledge base for hydropower development in the Indus basin. Our method could similarly be adapted to inform hydropower development in other basins across the globe.

The Continental intercalary groundwater is highly sought for its water as resources hugely mobilized in Northern Sahara. A very high flow rate and output pressure characterizes this underground water. It amounts from 50 to 400 l.s-1 for the flow, and from 5 to 40 bar for pressure. A survey of the Northern Sahara Aquifer System was essential to prove the existence of this potential. This energy appears into the artesian form, which remains very considerable for a very long time in most drilling. We have realised that this energy is immense, as well as the expanded volume of the groundwater, and the importance of its use in agriculture. Unfortunately, this potential remains untapped to this day and the energy of this water is completely neglected. Several turbo generator and/or inverted pump (PATs) integration tests were undergone. The new concept of reflection with respect to the environment and sustainable development has led us to structure our work towards the extension of this potential in order to extract the exploitable energy.

This paper proposes hydropower potential sites for several islands located in the South China Sea. The islands depend mainly on diesel-fuel for electricity generation. As a result, the generating company exposed to diesel high and unpredictable market prices, high operation and maintenance costs, and possible risk of fuel spills. Therefore, reconnaissance studies were conducted through topographic maps and hydrological studies in order to determine the potential sites suitable for development of micro-hydro and pico-hydro generation. The studies conducted for 14 islands in the South China Sea with a total of 51 investigated sites. The result indicates that 24 sites identified to have micro-hydro potential and 22 sites have pico-hydro potential.
